The invention aims which, through the instrumentality of a simple mechanism, will, attain a secure hold on a hose or other object, it being possible to releasethe hold readily, upon occasion.

Figure 1 shows in longitudinal section, a device constructed in accordance With the invention, parts appearing in elevation; Fig

ure 2 is an end elevation wherein the hose is omitted.

Thestructure includes an annular body 1 provided at oneend with a threaded bore 2 and supplied at its opposite end with a sleeve 3 having longitudinal slits 4 defining compressible arms 5, the sleeve 3 being tapered toward itsiree end, and threaded,

.F'erted between the nipple 9 and the sleeve.

the hose abutting at its inner end against the body 1. 'iVhen the collar 8 is advanced along: the arms 4%. the arms Wlll be compressethand the ribs 7 will engage the hose the hose thus being bound between the arms 3 and the arms 11, the last specified arms yielding slightly; and afi'ordin g; With the arms fl, a strong hold on the hose. The

to provide a structure it collar 8 is" numeral 1 1 denotes a oonneotion vvhich may formflpart of a turbine, one end of the connection being threaded into the bore 2 ol: the

body '1. The connection 1 1 abuts against the inner end of the nipple 9, and the nipple, therefore forms a stop for the part 14;.

Having thus described the invention, what isclaimed is 1 Y 1. In a device of the class described,'an annular body provided With inner and outer compressible arms the outer arms being' I tapered and threadech and a nut threaded '3 on the outer arms, the inner arms being spa'eed from the outer arms, for'the reception of a tubular member.

2 In a device of the class described; an annular body provided at one end with a threaded bore and supplied at its opposite end with. a tapered sleeve which is externally threaded, the sleeve having, longitudi 0o nal slits defining compressible arms; a nip ple threaded at one end into the bore of the body and having its opposite end disposed *1 wit/fin the sleeve, said opposite end'of the nipple having longitudinal slits defining-" compressible arms; a tubular members threaded into the bore of the body'and abut-I ting against one end oii'the nipple; a tubular the arms of the nnWAnn iv .i'onns'ron. f
